Application flay 26,

' Afurther object is to'provide an apparatus of the classdescribed having the novel con f:

struction, combination, and design. of parts hereinafter described, and illustrated in the" accompanying drawings.

In the drawings-- Figure 1 is an ehdvieWof the apparatus,-- the-upper portion of the housings and doubl'er mechanism being omitted since it is standard mechanism and forms no part of this invenzi and a clutch C.

Figure 2 is a sectional elevation taken on the line II-II of Figure 1.

Referring more particular ly to the drawings the numerals 2 and 3 designate the doub ler side housings which are spaced apart which are connected together by transverse members 4 and 5 and by otherstructural members adjacent their upper ends (not mg 191 1 ,hold the clutch member 33 out of shown). v.

The sheets or plates to be doubledare passed between the housings 2 and 3 and are adapted to be forced down between azpair of doubling rolls 6 and 7 by'the doubling knife 8.

'. The truck'A comprises a A pair of guide plates 9 and 10. are arranged transversely between'the housings 2 and 3'and are adapted to receive the-doubled sheetsor plates and guide them downwardly onto a wheeled'carrier or'truck A located in a passageway B, between the lower portions of the side housings 2 and 3. flat chassis or body 12,,axle s 13, and flanged wheels 14. A

v hand brake mechanism is provided tolfrictionally engage the one pairofiwheels. so as to normally resist free movement of the truck, 'andcom risesa brake shaft 15 journaled on the chassis 12 and provided with a hand operating lever 16 having a ratchet lock 17. A

pair ofbrake shoes 18 are carried by the shaft 15 and adapted to engage the truck wheels. The brake mechanism is adapted to be set so as to'retard the-movement of the truck A and prevent coasting thereof while, at the-same time, permitting the truck to move when force is applied thereto.

A sheet on plate sto thetruck chassis 12 ad iacent one end and extends upwardly therefrom, and is adapted to.

"support the doubled sheets on plates in edgeably'mounted ina supporting housing 23 se "'A crahkshaft 24 is journale'd in bearings urged toward the jaw member 31 by a coiledguide plates 9 and 10;

wlse position as they are deliveredvonto the truck; Y l A packing member is provided for packing .the sheets or plates forwardly toward the stop head 20, and comprises a head portion' O0 21 and stem portionf22. The stem 22 is slidcured to the transverse member 4.

25 on the memberl4 and has its crank portion 26'connected to the rear end of the stem '22 by a connecting rod 27. The shaft 24 is adapted to be operated'by a motor 29 througha-set o'f standard reducing gearings' indicated at 30,

The clutch C has one j-aw,member 31fi xed ing and its other jaw member 33 slidably mounted on the crank shaft 24 and normally spring 34.- The member 33 is provided'with a spiral groove 36in'wl'1ich a clutc-hoperat- 'n 3% is adapted toride to force and a einent with the member L31.

The pin 37 is connected by a connectin 7 link 38 with a counter-weighted lever 39"se cured io-n rock shaft 40 journalcd inb'carings on the transverse member 5. A pair ofopcrating levers '41 "are secured to theshaft 40 i and have their. free) ends extending'through slots 42 in the guide plate 9 and into the path of the sheets or plates passing between the In operation, the. carriage or truck A is backed into the passageway B between the housing sides 2 and3 until'the head 20 is close to or in contact with the packing head 21 and-the brakes 18 are set to hold the truck against free movement from this position! The doubler mechanism is then set in' mo- 1 tion as is also the motor 29 for driving the As a sheet or plate is doubled and forced through the rolls 6 and 7 it-will pass between the guide plates 9,and 10 and trip the levers 41 which will rock the shaft 40 so as to raise the lever 39 and link 38 and thereby lift the pin 37 from the slot or groove 36 in the clutch member 33. As the pin 3'1 is lifted'from the groove 36 the clutch member 33 willbe forcedinto driving connection with the I co-acting clutch member 31 by the spring 34, thereby causing rotation of the crahk shaft 24 which in turn will reciprocate the packing head 21. As the head 21 is moved rearwardly the doubled sheet or plate will drop onto the car riage or truck immediately in front of the head 21, and the head 21 on its forward movement, will engage and push the doubled sheet or plate forwardly toward the head 20 and into contact with the previously packed sheets on the truck, so as to force the sheets into packed engagement. The stroke ofthe head 21 is constant. Therefore, the truck A will be moved forwardly an amount equal to the thickness of the doubled sheet delivered in front of the head on each of its rear strokes.

The clutch-pin .37 will automatically enter the groove 36 after the doubled sheet has passed beyond the levers 41, due. to the urging of the counter-weighted lever 39,-and will retract the clutch member 33 so as to stop the.

shaft 24 after one complete revolution. A WVhile I have shown and described one specific form of my invention it will be un derstood that I do not wish to be limited thereto, since various modifications may be made without departing from the scope of plates comprising, in combination, a housing my invention, as defined .in the appended claims Y I claim- 1.
